CHARLES I. THOMAS, OF WILKES-BARBIE, PENNSYLVANIA.

v ADJUSTABLE SHADE-BRACKET.

Specification of Letters Patent;

Patented July 18, 1916.

Application filed November 1, 1915. Serial No. 59,005.

To all whom it may concern:

Be it known that I, CHARLES I. THOMAS, a citizen of the United States, residing at Wilkes-Barre, county of Luzerne, and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Shade-Brackets, of which the following is a specification.

This invention relates to adjustable window shade and curtain pole brackets.

My'object is to provide a simple, neat, and eiiicient shade roller and curtain pole holder of improved construction and combination of parts which can be extended or contracted to any desired degree to adapt it to be-inserted between the jambs or sides of a window frame and thereafter quickly and easily tightened to clamp its end parts against the sidesof the frame, so that it is adapted to fit frames of different widths without requiring any special fasteners to secure it in position.

The construction of my improved holder is-such that it is adapted for supporting shade roller brackets, or curtain pole brackets, or combined shade roller and curtain pole brackets so that it may be adapted forsustaining a shade holder alone, a curtain alone, or both a shade roller and a curtain ole.

The brackets for the support of the shade roller 0r curtain pole, or both, are adjustably mounted on the holder so that they can be set to accommodate any desired length of shade roller or curtain pole.

In the accompanying drawings I have disclosed certain einbodiments of the invention and have described them in detail hereinafter, but as the invention is susceptible of various modifications, the forms hereinafter set forth and which are shown in the drawings, are to be considered as illustrative, rather than restrictive, of the scope of the invention.

In the accompanying drawings: Figure 1 is a plan view with certain parts in section, showing the device in position and a shade roller carriedthereby; Fig. 2, a detail section on. line 22, Fig. 1; Fig. 3, a detail of a part of the device, showing the adjusting and securing means therefor; Fig. 4, a detail of a modification; Fig. 5, a detail of another modification; Fig. (5, a detail cross section on line 6 6, Fig. 5; Fig. 7, a detail view of the ad usting means of the form of Fig. 5; Fig. 8, a view of a modification of Fig. 1; Fig. 9, a View of another modification employing a fiat rod; Fig. 10, a detail view of the modification of Fig. 9; Figs. 11 and 12, details of the parts at the ends f the construction of Fig. 10; Fig. 13, a view of another modification, parts being in dotted lines and in section; Figs. 14 and 15, details of certain parts of the modification of Fig. 13; Fig. 16, detail views of different forms of brackets for use with square rods or holders; and Fig. 17, detail views of brackets for use with flat rods or holders such as shown in Figs. 9 and 10.

Referring first to Figs. 1, 2 and 3, the bracket holder consists of two square sections 1 and 2, the latter being provided with teeth 3, and a sleeve 4 secured at 1" to the section 1 and having a square interior or bore receiving the section 2. A spring-actuated locking catch 5, carried by the sleeve 4, is adapted to engage with the teeth 3 so that an initial adjustment of the parts 1 and v 2 can be readily obtained to bring the holder to a length adapting it to be received between the jambs or sides 6 of the window frame. A clamp plate or member 7 is adapted to bear against one side of the j amb 6 and contains a plate 8 which serves as an abutment for the end 9 of the member 1, the latter passing through a square. opening 10 in the clamp plate 7. The end of the member 2 is internally screw-threaded at 11 and engaged with this screw-threaded bore is an adjusting screw 12 having a head 13 and journaled at 11 in a clamp plate 15 which bears against the other side of the jamb 6. The head 13 abuts a plate or member 16 contained within the clamp plate 15.

Splined or pinned to the adjusting screw 12 is an adjusting nut 17.which is provided with holes or pockets 18 in its periphery for the reception of a nail or suitable implement, whereby the said nut and the screw 12 may be rotated for the purpose of clamping the plates 7 and 15 against the walls of the jamb 6. After the necessary clamping has been effected, a jam nut 19 which is internally threaded and engaged with the screw 12, may be turned up tight against the end of the member 2, thus insuring the rigidity of the holder and its retention in position.

S'lidably mounted on the members 1 and 2 are shade brackets 01' mountings 20 and 21 which have set-screws 22 adapted to engage the sections 1 and 2 for the purpose of holding these brackets where positioned.

i The brackets are square in their bore and point thereof.

hence do not turn on the square members 1 and 2. The shade roller, which is conventionally shown at 23, is mounted in the brackets 20, 21. Consequently, a shade roller of any' desired length may be carried by the brackets 20 and 21 as the latter can be shifted along the members 1 and 2 and held where desired by the set screws 22. The nut 19 is preferably provided with openings like the openings 18 and for the same purpose.

In the form shown in Fig. 4, the sections 1", 2*"- are round and the adjusting mechanism is comprised solely in right and left hand screw-threaded portions'24, 25, on the sections 1, 2 and a sleeve 26, having corresponding internal screw threads, receives the screw-threaded parts 24, 25, so that by turning the sleeve, the sections 1", 2 may be spread apart or drawn together. The ends of the sections 1*, 2 are received in clamp plates 7 15 and are provided with collars 27 which bear against said clamp plates. The shade brackets or mountings are shown at 28 and have set screws 29 for securing them to the sections 1, 2 at any desired In the modifications shown in Figs. 5, 6, 7, a square rod or member 1 extends from one clamp plate 7 to the other 15". Oneend of the member 1 is received in a square socket 10 and there may be provided as many filling washers or disks 30 as necessary to compensate for the play required to insert the device between the jambs 6. lhe other end of the member 1 is provided with. a screwthreaded extension 31 which engages the screw-threaded bore 32 of an adjusting member 33 which has a journal 34 rotatably mounted in the clamp plate 15 and adapted to be turned by a. handle or lever 35. Having -first 'inserted the device of Fig. 5 between the jambs 6, the lever 35 is turned to force the clamp plates 7*, 15 against the jamb. Shade brackets or mountings 28, with set screws 29, such as shown in Figs. 1 and 4 are provided on the member 1", although not shown in Fig. 5.

1n the modification of Fig. 8, the construction is the same as in Fig. 1, with the exception that the section 1 is, like the section 2, provided with teeth 3, and. the sleeve 4*, instead of being fixed to the section 1, fits loosely over said section and is adapted to be engaged therewith by a spring locking catch 5" similar to the catch 5.

Referring to Figs. 9, 10, 11 and 12, the holding rod or member 1 is fiat and pro- 'vidod with beads along its upper and lower edges and is preferably of wood. At one end there is a cap 40 which fits over the end of the rod 1 and is provided with a clamp plate 41 having points 42 to engage one of the jainbs of the window frame. At the other end there is fitted over the holder or rod 1 a cap 43 which is internally screwthreaded at 44 in line with a concavity 45 in the rod 1 An adjusting screw 46 carries an adjusting nut 47 and a jam nut 48 similar to those shown in Figs. 1 and 3 at 17 and 19. Swiveled at 49 on the end of the screw 46 is a clamp plate 50 substantially similar to the clamp plate 41. This form of the invention is positioned and set by first engaging the teeth 42 with the left-hand jamb of the window and then turning the adjusting nut 47 to engage the clamp plate 50 with the right-hand jamb, after which the jam nut 48 is screwed up against the cap43.

In the modification shown in Fig. 13, the construction of the sections 1 and 2, sleeve 4 teeth 3, 3, and locking catches 5, 5*is the same as disclosed in Fig. 8. At the lefthand end of the section 1 is secured a clamp plate 51 to engage the left-hand jamb of the window frame. The outer end of the section 2 is screw-threaded at 52 and there is mounted thereon an internally screwthreaded sleeve 53 to which is rigidly secured or formed integral, an adjusting nut 54 which is similar to'the nuts 17 and 47. On turning the nut 54, the sleeve 53 advances along the screw-thread 52. Loosely mounted on the right-hand end of the sleeve 53 is a clamp plate 55 of the form shown in Fig. 14. The advance of the sleeve 53 forces the points of the clamp plate 55 into the right-hand jamb of the window frame.

In Figs. 16 and 17, I have illustrated some of .the brackets which may be employed in connection with the different forms of the invention for the purpose of supporting shade rollers or curtain poles, or both. in Fig. 16, the brackets are for use on those forms of the invention such as shown in Figs. 1, 3, 5, 8 and 13, which employ holder sections 1, 2, that are square in cross-see tion. In the'form shown in Fig. 17, the brackets are adapted for use with fiat hoiders or rods, such as shown in Figs. 9 and 10. Figs. 16 and 17 illustrate only one of brackets in each instance, it being understood that there is another bracket corresponding thereto except that a hole in stead of a slot is provided to accommodate the shade roller. Furthermore, the different brackets of Figs. 16 and 17 may be pro vided with any suitable fasteners for curing them in position, such as the screws shown at 22, Fig. 1, for instance.

Referring to Fig. 16, the bracket 56 is adapted to carry a. shade roller and a cnrtain pole on the face of the window jamb or casing. The bracket 57 is substantiail; similar to the bracket 56, except that it projects straight forward. The bracket 58 is adapted to carry one .shade roller and two curtain poles. Bracket 59 is intended. to

carry two heavy shade rollers and bracket 60 one shade roller.

Referring to Fig. 17 the brackets 61, 62,.

63, 64 and 65 correspond, in use, to the brackets 56 to 60, but they are provided with clip bases adapted to slide on the flat provided with any fastening means, such as a screw, to clamp them to the rod on which they slide.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is v 1. In a pressure-retained window shade or curtain pole support, the combination with clamp plates or members, adapted to bear against the inner faces of the jamb of a window frame, of a shade roller or curtain pole bracket holder comprising relatively adjustable sections for which said clamp plates constitute end pieces, means forsecuring the sections in different positions of relative ad'- justment, shade roller or curtain pole brackets adjustably mounted on the respective sections, and a screw-threaded stem, an

adjusting nut for turning the stem, and a jam nut on the stem constituting a supple mentary screw pressure means for effecting a secondary expansion of the shade or curtain pole support for the purpose of exerting pressure on the clamp plate to hold them against the inner faces of the jamb, said jam nut being adapted to bear on the end of the section to prevent turning of the stem after adjustment.

2. In a pressure-retained window shade or curtain pole support, the combination with clamp plates or members adapted to bear against the inner faces of the jamb of a window frame, of a shade roller or curtain pole bracket holder comprising relatively adustable sections for which said clamp plates constitute end pieces, a sleeve which receives both of said sections, catches and teeth for fastening the sections to said sleeve after relativeadjustment, shade roller or curtain pole brackets adjustably mounted on the respective sections, and supplementary screw pressure means for effecting a secondary expansion of the shade or curtain pole support for the purpose of exerting pressure on the clamp plates to hold them. against the inner faces of the jamb. b

3. In a pressure-retained window shade or curtain pole support, the combination with clamp plates or members adapted to bear.

against the inner faces of the jamb of a window frame, of a shade roller or curtain pole bracket holder comprising relatively adjustable sections for which said clamp plates constitute end pieces, a sleeve which receives both of said sections, catches and teeth for fastening the sections to said sleeve after relative ad ustment, shade roller or curtain pole bracketsv adjustably mounted on the respective sections, a screw-threaded stem, an adjusting nut for turning the stem, and a jam nut on the stem constituting a supplementary screw pressure means for effecting a secondary expansion of the shade or curtain pol'e support for the purpose of exerting pressure on the clamp plates to hold them against the inner faces of the jamb, said jam nut being adapted to bear on the end of the section to prevent turning of the stem after adjustment.

In testimony whereof, I hereunto afiix my signature.
